Outlook/Schedule+ Error "req32.cfg could not be opened" [Q195205]

SYMPTOMS
When using Microsoft Schedule+ as your primary calendar in Microsoft Outlook,
you may receive the following error message when attempting to start Schedule+
from within Outlook:

The file <drive>:\<OS>\Forms\Configs\Req32.cfg could not be
opened.
Microsoft Exchange Forms Registry.

The '\Configs'-folder does not exist and the 'Req32.cfg' file resides in a different
folder.

CAUSE
The Microsoft Exchange client is not installed on this computer.

WORKAROUND
Include the Exchange client during the installation of Schedule+.

MORE INFORMATION
The Exchange client controls the workgroup functionality of Schedule+. Without
it Schedule+ is installed in standa-lone mode. Outlook does not detect whether
Schedule+ has workgroup capabilities when being configured to use Schedule+ as
its primary calendar. It only requires that Schedule+ be installed and
operational.

If you start Schedule+ from the Start, Programs menu, you are not presented the
dialog box to choose the options to work in group-enabled mode or to work alone.
It provides the options to create a new schedule file or to use and existing
schedule file but does not offer the option to NOT have a schedule file on this
machine. This is because Schedule+ does not have online capabilities without
Exchange client being installed.
